CONCRETE PAVEMENT.

SPECIFICATION forming part of Letters Patent No. 256,383, dated April 11, 1882.

Application filed March 1,1882 (No specimens.)

der such pavement practicable forstreets. For

this purpose I construct my new pavement with grooves running transversely across the street from curb to curb, so as to afford a good foothold for horses and other draft-animals. I also form my pavement on a convex bed, so that when the cement has set and a portion of the bed should be washed away the pavement, which forms an arch, will still retain its position against a considerable pressure.

In the accompanying drawings, Figure l represents a plan or top view of a street-crossing provided with my pavement. Fig. 2 is a transverse vertical section in the plane x .r, Fig. 1. Fig. 3 is a longitudinal vertical section in the plane y y, Fig. 1, on a larger scale than the previous figures.

Similar letters indicate correspondingparts.

In the drawings,the letter'A designates the roadway of a street. B B are the sidewalks, and O O the curbs. curbs contains my new pavement, which is laid in sections D, as described in my Patent Reissue No. 4,364, above named, each section being provided with chamfered edges a a, as shown in Fig. 3, so that when the pavement is complete V-shaped channels b extend transversely across the street from curb to curb. At the street-crossin g A the v -shaped channels of my The space between the the dust does not settle therein as firmly as it would in rectangular grooves.

In laying my pavement I prepare the bed E so as to present a convex surface, and on this bed I spread the cement, either in molds or between movable joists of the proper thickness,

and before the blocks have set I chamfer their edges, so as to produce the V-shaped channels.

By making the bed convex my pavement, when ready, forms an "arch, which abuts against the curbs, and if the bed should be partially washed away from under the pavement, my pavement is still able to sustain a considerable weight without giving way. For this reason I am enabled to build my pavement on a removable center or foundation when such is desirable.

The pavement described in my Patent Reissue No. 4,364 was intended particularly for sidewalks or walks used solely by pedestrians,

and on account of its smooth surface I could not apply the same to the roadways of streets. By my present improvement the pavement is rendered eminently fit for roadways.

I distinctly disclaim in my present appliea- JOHN J. SOHILLINGER.
